Without the signature campaigns, many members would continue to write on the forum but there would be a serious decline in quantity. You can see many members without signatures writing on various topics. They may look few because they don't write very often as others, but in fact there are many users without a paid signature. You can think about what the overall forum will be like by looking at the messages in the sections where posts are not counted for paid signatures.
Partially true, but for me personally, I look for topics that interest me more, if I don't find enough of them, I won't post on arbitrary subjects no matter wearing a paid sig or not. And when I'm bored from forum, I'd go do the naughty things instead.
It's natural honestly, we all need to have something in our hands to play with and keep us busy, or we would try to find something ourselves.
This kind of reminds me of an advice I gave to my girlfriend's brother, his wife was trying to cheat on him, and since I couldn't tell him directly, I told my girl that her brother needs to buy the wife a dildo, so that she can keep busy when the husband is at work. I think that conversation ended in bed, naked. Typical move from me to start such convo just to get in her pants.😂😂
